To all 'whom it may concern: n

Be it known that I, Louis KEssiEn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filling-Tubes for Explosive-Liquid Receptacles, of which the following 1s a description.

My invention belongs to that eneral class of devices known as filling tu es, and relates particularly to that class of devices that are employed on tanks, cans and the like for holding the gasolene, naphtha, benzin, or other explosive liquids provided with means for guarding against explosion. The invention has among its objects the production of a device of the kind described that is safe, simple, eilicient, compact, durable, for use wherever found applicable. It has among its further objects the productionof an im roved device of the kind described that will permit the air to escape from the tank while filling, and which will not be injured by the force or shock of .the fluid entering the tank.

To this end my invention consists in the novel construction, arrangement and combi-` nation of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding Figure 1 is a sectional view through my improved fillin tube and closure therefor taken substantially on 'the line 1-1 of Fig. 3;

ig. 2 isa top plan view of the same;

Fig.. 3 is a sectional view taken substantially on line 3--3 of Fig. 1; Fig. 4: is a sectional view taken substantially on line 4-4 of Fig. 1, and

Fig. 5 isy a sectional view taken substan- 1 isfa tube of suitable material having its. upper end flanged as at 2, and extended at 2', and suitabl threaded as shown, it being understood 4t at 4the flange and threaded portion may 'be formed integral with the tube, as shown or a separate portion secured thereto. The tube is arranged in the tank 3, and secured thereto in any' preferred manner. As previously mentioned the same is threaded and thus removably secured to the Referring toV the drawings,

' side maintainingy the 'maintained shut `by a-spriiig=26fibea tank, the flange 2 being ordinarily formed similar to a nut, so as to permit its being readily engaged by a suitable wrench, or the equivalent. The tube is shown open at its lower end, and provided with a wire gauze 4, which may be reinforcedand' protected by the coarser wire gauze 5, the coarser gauze preventing the fine gauze from being fractured accidentally. The same is also formed with apertures 6 thereabout, preferably near the bottom, which are covered by wire gauze 7, and which may be reinforced if desired. I have shown the gauze 4 and 5 and the lower end of gauze 6 secured in place by a flanged collar 8, the parts bein cured to the tu e. The tube is also'shown with a series of openings or apertures 9'arranged substantially near the upper end of the tube, these being covered by gauze 10, secured in place on the tube in any desired manner. j

Arranged within the tube 1 and spaced therefrom is an inner tube 11, theV upper end 11 of the same extendin to adjacent the top 2 of the oute` tube. he innertube is formed with a flange 12, of aI sizeto closely t the inner wall of the tube 1, `and with ribs 14 at the top for spacing the upper end from thetube as at 13 and `maintaining the inner tube against rocking or displacement. The inner tube maybe inserted and secued in place in any desired inanner. The ube 11`is provided with a series of apertures or perfor-ations 15 below the lpartition 12, the same being of any desire shape and size, and the bottom is preferably closed as at 16'.

The closure on the tube may be of any desired construction, that shown comprising a cap 18 having an opening 19 therethrough, which is normally closed by the cover 20, suitable packin 21 being arranged between the same and t e tube. The packin may be of leather or other suitable materia an is shown secured to the top 20. The top or cover 20 is provided with one or more lugs 22, and the same pivotally securedto an. arm or lever 23 by a pin 249, or the equivalent. The arm 23 is pivotally car ried by the shaft or in 24, supported-bg the lugs 18 on partl acollar 251oneac arm 23-a`gainstfiate eral movement. The closure is normall soldered or otherwise se-v against the arm 28. or by equivalent moans for llal pai-pose.

The cover :.ll is formed with a depending tubular part 2li. and with an aperture 30. At the inni-r side ot' the aperture is formed a valve scat arranged to ro )crate with the valve 31, which is normally maintained closed b v the` spring 3&2, or tie equivalent, which bears against or is supported by the rap 33. which is formed with a shoulder, as shown. The cap 33 has an opening 34 therethrough.

To fill the tank arm 23 is raised, the same being formed with a convenient end 28 for example, and with a stop 27, arranged to bear aga-inst the plart 18 and limit the opening movement. he liquid may be poured into the tube and passes through the a'pertures 15 between the tubes. Owing to the bottom 16 the same does not fall directly on the gauze 4, so that that is not injured by the shock. The bottom 16 also protects the' gauze in case measuring sticks or the like are inserted in the open end of the tube. It passes through the apertures 6 and out through the side and bottom wall. through the gauze 7, 4 and `5, into the tank. The air in the tank, as the same is filled, escapes through the openings 9, and up through the passages 13 to the outside. Aftcr the tank is filled to the desired level the arm 23 is released and the closure automatically drops into closed ostion. In case of any pressure in the tan caused for any reason whatever, when the same reaches the point where it overcomes springs 26, the closure may open, relieving the pressure, after which the closure drops back into osition, closing the receptacle. As the iquid is drawn oi from the tank, air may enter through the aperture 30, thereby preventing' a partial vacuum that would interfere with the operation. It will be noted that the opening 30 is below the arm 23, so that dirt does not readily enter the same and close it up. Itis impossible for any llame to get through the .gauze covering the various apertures and igniting the contents of the tank. The device therefore s an eilicient safety device, preventing the contents of the tank from becoming ignited and exploding. Owingtothe method of attaching the cover, the cover or closure cannot be mislaid after lling the tank, nor can it be left of through forgetfulness and negligence. Owing tothe valved opening 30 the contents of the tank may be drawn off without creating a vacuum in the tank, and consequently impairing the supply. As constructed, the tube is extremely durable.

Having thus described my invention it is obvious that various immatorial modifications may be made in the same without deartin from the spirit of my invention; ence do not wish to be understood as limltm'g myself to theexact form,` construction,

arrangement and combination of parts here in shown and described, or uses mentioned, and l reserve tho right t0 prosecute in divisional application or aj'ipliuations certain subject matter herein disclosed, but not specifically covered by the claims.
